there are lots of "features" about scopes to consider. while there is some merit to *quality* variable power scopes (not cheap!), most shooting/aiming can be well accomplished with a *good* fixed power scope. consider that the 4x to 10x scope was - and to a fair degree, still is - the military standard sniper favorite. fixed scopes are also typically more durable, with less to "go wrong" than a variable power, not having to settle for a 2nd focal plane, and better glass with less distortion. besides the glass/optics, also consider the turrets and their degree of adjustments.

i would highly recommend the swfa ss line of fixed power mrad military scopes and my fave for 100 yards and out to 1000 yards is still their $300 classic 10x42 tactical mrad 30mm. check it out ...
